Dorm head of Asakami clan, and their most powerful member in OLYMPUS. Famous for the band he has started, and thus there is lot of knowledge floating about him. However, it is not known what information can be trusted, and what not, so the simple noise around him and his abilities is enough to make calculating his true abilities and power a futile task. Still, seems that he is known to use, at least, electrokinesis.
It seems that despite being young, he is trusted by the elders of the Asakami clan, and this was one of the most important reasons of why he was chosen as the Dorm Head. And, if anything can be judged from the fact that his cousin managed to destroy a colossal bridge with her Mystic Eyes, it is clear that the power Kazuya holds inside him is one to be reckoned with. After all, those who have seen him in battle liken him to the god of Thunder, Raijin, of ancient Japanese tales.
Said to have the most powerful ESP among the Dorm Heads.
